Die 10€ Wahrheit über 1.000€ Messe Smart Home Gadgets

What kind of smart home user are you? Find out: https://tally.so/r/wo40GV?utm_source=... Want to really understand ESPHome and YAML? ESPHome Masterclass: https://tally.de/go/mk-53messe26 Do high-end smart home gadgets really only rely on expensive "premium" components? At Light + Building and embedded world, I'll be taking a look at the most exciting products and mentally breaking them down into their building blocks: What sensors are inside, what chips are used – and what can we, as makers, replicate ourselves with inexpensive standard components? In this deep dive from the trade fairs, you'll see the best ideas for presence detectors, weather stations, energy monitoring, and smart home control. Included: KNX highlights, manufacturer insights, and the harsh reality of why some products are so expensive (and where exactly our DIY approach still makes sense). ``` Check out the videos and short videos from the trade fair here:    / @haus_automation      / @smarthomeyourself      / @flotomation   Video highlights: Presence detector overload: PIR vs. radar/mmWave, multisensor technology (VOC, temperature, humidity, light), thermopile temperature measurement, and smart features like orientation lights Professional weather stations explained: Wind measurement without mechanics (thermal/NTC principle), ultrasound for wind direction, optical rain detection, heating against dew/snow, GPS for sun position Garden irrigation and soil sensors: what real systems can do (and what we want to solve better locally) Energy & distribution: smart circuit breakers/MCBs, more precise current measurement, safe integration (please only with a qualified electrician) Switches, buttons, surfaces: why "real materials" are booming and what's behind it Smart Home Displays: Why many panels cost around €1,000 and whether E-Ink is a better first step embedded world Takeaways: Which microcontrollers, modules, and displays (e-paper) are really exciting for our next DIY projects Your contribution: Which project should be featured next on the channel? 1) Next-Gen Presence Detector (slimmer housing/circuit board, possibly battery-powered) 2) DIY Weather Station (useful sensors instead of overkill) 3) Smart Home Display (E-Ink or Touch) Write your priority in the comments. #Alkly #SmartHome #HomeAssistant #ESPHome #DIY #KNX #LightAndBuilding #EmbeddedWorld #PresenceDetector #mmWave #PIR #WeatherStation #Matter #MQTT #IoT https://alkly.de/ 💬 Did you like the video?
